Abstract

Provided is a heating and hot water supply device. The heating and hot water supply device includes: a combustion part; a heat exchanger; a circulation passage; a circulation part; a bypass passage; a distribution means for distributing the heating medium to the circulation passage and the bypass passage; a hot water supply heat exchanger; a water supply passage; and a hot water supply passage (21). The distribution ratio of the distribution means is adjustable so as to correspond to a heating operation, a hot water supply operation, and the simultaneous heating and hot water supply operation. The heating and hot water supply device includes an operation part, which heats the heating medium to one or more heating terminal setting temperatures and circulates the heating medium, and switches a setting of the one or more heating terminal setting temperatures to be increased by a prescribed temperature during the simultaneous heating and hot water supply operation.
